Reddit mentions of Miniature Barrel Hinges

Here is a box that I made.

I used magnets to keep it shut, but I've done similar boxes with hinges on one side and a magnet on the other. For hinges, I'd use mini barrel hinges. They will be less intrusive. I didn't feel like ordering magnets online, so I went to Lowe's and bought some fridge magnets that look like push pins and cracked the plastic to pull out the magnet. They are a nice size. The pillow is made by taking two foam hair rollers and sewing some nice fabric around them. The ring will sit in the crack between the two. I wouldn't use fabric that is too crazy though. You want the ring to be the focal point.

I made one of these a year ago and used barrel hinges. Worked pretty good. Here are the ones I got. Be sure to be extra super careful when lining up the holes. Those rockler dowel centers suggested by doitdoitdoit look like a good idea.
